On Sunday (Feb. 19), Soulja Boy jumped on his Twitter account and slammed Brown for not signing the paperwork to solidified the boxing match. In a series of tweets the Atlanta rhymer lambasted Breezy for being scared to fight him.

“I can’t believe this n---- scared to fight me. Sign the contract Bitch Ass n----, set up the boxing match,” he tweeted.

“N---- talked all that s--- just to back down and not sign the paperwork. Not about that life. No action. Don’t wanna hear about this ever,” he continued. “Obviously, he don’t wanna fight, so I’m gonna leave him alone. Beef over just tell him don’t call my phone over a girl. That 2nd time.”

He concluded his rant by writing, “I couldn’t wait to knock that n---- out now about y’all tweet him and ask why he backed out? I’m back to the studio. With yo bitch.”

Although Brown has yet to address why he's not signing the paperwork, he has a lot on his plate right now. The R&B singer is planning to launch “The Party Tour” real soon. The trek boasts an all-star lineup of rappers: 50 Cent, French Montana, Fabolous, O.T. Genasis, Kap G and Casanova.

There's no word on when Brown's tour will begin but we can guess that it will probably start in the spring or possibly summer.

Either way, it would have been interesting to see SB and Breezy duke it out in the boxing ring. But who knows it might go down. We'll have to wait and see.
